Mechanical manipulators are modeled by a set of coupled nonlinear second order differential equations. If a complete model is available, model-based controllers can decouple and linearize the manipulator dynamics. However, since there is a degree of uncertainty in the manipulator model, a model-based control scheme which is robust against modeling error and disturbance is required. This paper proposes a robust control scheme based on H control theory. The controller consists of a model-based controller followed by a H controller. Given a nominal model of the manipulator dynamics, the model-based controller approximately linearizes the manipulator dynamics. The H controller compensates for disturbances and unmodeled dynamics. Experiments on two link direct drive manipulator exhibit the effectiveness of the proposed H model-based robust control scheme.
